与自己竞争:在竞争性学习模型中引入自我互动
Competing with oneself: Introducing self-interaction in a model of competitive learning
摘要:
在参考文献1(A. Mehta和J.M. Luck,Phys.Rev.E60,5,1999),其中学习是结果相关的。每个人都在一对现有的策略或类型之间进行选择,由两个因素的组合指导:倾向于符合当地大多数,\em{and}偏好具有较高感知成功的类型\em{among its neighbors},基于其相对结果。在这里,提出了参考文献1的\em{interfacial model}的扩展,其中个体在基于结果的选择中额外考虑他们的\em{own}结果。三个可能的更新规则处理批量网站被认为是。相应的相图,在共存时得到的,显示系统偏离原来的界面模型。这些变体与参考文献1中的\em{cooperative model}之间可能存在的关系也被提及。
英文摘要:
A competitive learning model was introduced in Ref. 1 (A. Mehta and J. M. Luck, Phys. Rev. E 60, 5, 1999), in which the learning is outcome-related. Every individual chooses between a pair of existing strategies or types, guided by a combination of two factors: tendency to conform to the local majority, \em{and} a preference for the type with higher perceived success \em{among its neighbors}, based on their relative outcomes. Here, an extension of the \em{interfacial model} of Ref. 1 is proposed, in which individuals additionally take into account their \em{own} outcomes in arriving at their outcome-based choices. Three possible update rules for handling bulk sites are considered. The corresponding phase diagrams, obtained at coexistence, show systematic departures from the original interfacial model. Possible relationships of these variants with the \em{cooperative model} of Ref. 1 are also touched upon.
